Significantly more l2 cache 1 MB vs 0.25 MB 4x more l2 cache; more data can be stored in the l2 cache for quick access later
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Higher clock speed 1.8 GHz vs 1.3 GHz Around 40% higher clock speed
Better overclocked clock speed (Air) 2.12 GHz vs 1.4 GHz More than 50% better overclocked clock speed (Air)
More l2 cache per core 0.5 MB/core vs 0.25 MB/core 2x more l2 cache per core
More cores 2 vs 1 Twice as many cores; run more applications at once
More threads 4 vs 2 Twice as many threads
Better overclocked clock speed (Water) 1.8 GHz vs 1.4 GHz Around 30% better overclocked clock speed (Water)
